摘要
水库网箱养鱼从20世纪90年代初期规模和密度越来越大,严重的污染了库区及周围环境的水质。文中系统性地分析了水库网箱养鱼的污染状况,并以山东周村水库为例进行了实际监测。揭示了网箱养鱼的污染来源,水质污染的原因及程度。分析表明,水库网箱养鱼污染主要来自大量投放的饵料、肥料、鱼病防治药剂和鱼类自身的代谢产物,其不仅污染了库区水质而且对周围200 m范围内的水质产生了影响;文末提出了改善水库网箱养鱼水质的措施和对策,供有关管理部门参考。
Over the recent years,the scale and density of fish culturing with cages in reservoirs have been increased rapidly,and the water quality in reservoir areas is polluted seriously.It is showed here by analyzing that the enormous baits thrown and the metabolites of fish itself have caused the significant influence on the water quality.At last,the measures and strategies are put forward for improving the water quality in reservoir areas for fish culturing with cages.
